SPECIFICATION forming part of Letters Patent No. 741,067, dated October13, 1903. Application tiled May 18,1903. Serial No. 157,683. (Nom'odel.)

To EaZ-Z whom, it may concer-71,:

Be it known that 1, JOHN FRED PATTON, a

citizen of the United States, residing at Macon,in the county of Bibband State of Georgia, have invented a new and useful PhotographicRetouching-Frame, of which the following is a specification.

This invention relates to photographic retouching-frames; and theobjects thereof are to provide in a photographic retouchingframenegative-holding devices into which the negative may be readilyinserted, and by means of which the negative will be securely held, andtov provide means for readily shifting the negative into differentpositions, as required in the retouching process.

Vith the above objects and others in view, which will appear as theinvention is more fully disclosed, the same consists, generallyspeaking, in a rotatable base plate upon which are carried adjustablespring-actuated clamping devices bymeans of which the negative issecured in position over a central opening for the transmission oflight.

In the accompanying drawings is illustrated one form of embodiment ofthe invention capable of carrying the same into practical operation, itbeing understood that changes may be made in the form, proportion, andexact mode of assemblage of the elements therein exhibited withoutdeparting from the spirit of the invention or sacrificing any of itsadvantages.

In the drawings, Figure 1 is a front View of the retouchingframe. Fig. 2is a rear view. Fig. 3 is ahorizontal section on the line 3 3 of Fig. 2.Fig. iis a vertical median section through Fig. 2.

Inthe drawings corresponding parts are designated by the same charactersof reference throughout the several views in which they appear.

Referring to the drawings by reference characters, 1 designates a ringhaving front and rear internally-disposed anges 2 and 3 and providedupon the rear surface thereof with four radially-disposed arms 4, eachprovided with an oblique slot 5 for engagement with a stud upon asupporting-frame. (Not shown.) v

6 designates a base-plate, which is circular in -contourand is rotatablymounted within the ring 1, being secured by the flanges 2 and 3. Thediskmay bev made of any suitable material, as a heavyleather board, thinsheet metal, or sheets of Veneer suitably united, so as to preventwarping, and may be covered, if desired, with any suitable material, ascloth of proper texture. To facilitate the rotation ofthe disk in theway provided for it between the Iianges 2 and 3 on the ring 1,depressions 8 arev provided on opposite sides of the central opening 7.

On either side of the central opening 7 in the disk 6 are provided apair of slots 9, which are parallel and extend from points adjacent tothe diameter of the disk perpendicular to said slots to points adjacentto the periphery of the disk. Y Slidably mounted upon the front surfaceof the disk are a pair of plates 10, each of which has a pair ofrearwardlydisposed lugs 11, which project through the slots 9 in theface of the disk and are bent over at the rear of the disk,as'willherein face thereof, which is adapted to engage with a series ofopenings 14 in the disk 6, and a handle 15, of suitable form to becaught between the thumb and foreiinger, is provided on the lower plateto withdraw the pin 13 from engagement with one of the holes 14.. Theupper plate is provided with a curved spring-lug'l, adapted to engagewith a hook 17 at the upper portion of the disk when it is desired tohold the upper plate out of operative position.

Upon lthe rear surfaceV of the disk 6 there are provideda pair ofspring-casings 1S, which have slots 19 provided therein Lo correspond inposition to slots 9, provided in the disk. The lugs 11 upon the plates10, which project through slots 9 in the disk, alsof'project through theslots 19 in the spring-casings 18 and are bent over the spring-casings,as best seen in Fig. 2. In each of the spring-casings IOO 18 is locateda spiral spring 20, connected at its ends with the lugs 11 upon plates10,which project through the casing in which the spring lies. l ln thisWay the plates 10 are so connected that the springs always exertianequal pressure upon each plate, and the plates maybe set in any positionrelative to the centralopening in the disk and remain in the position inwhich they are placed without fastening.

Between the spring-casings 18 on therear side of the disk 6 and adjacentto the side of the central opening 7 are provided a pair of angularretaining-strips 21tto hold a ground glass 22, such as is ordinarilyused in retouching-frames. The retaining-strips 21 are formed offlexible metal and are secured to the disk in'any desired manner, thelower ends being bent into contact with the disk, so as to prevent theescape downward of the ground glass when slipped into the ways formed bysaid strips, and the upper ends are adapted to be bent over the groundglass after it has been inserted, so as to holdY it stationary inposition behind the opening in the disk. Y

In using the retouching-frame, as hereinbefore described, the negativeis inserted between the two plates 10, which are slidably mounted uponthe disk G and are drawn together by means of springs 20, as alreadyexplained. The upturned lugs 12 upon' the plates 10 are hooked over theedges of the negative and hold it securely upon the plates 10. In orderto hold the negative at any desired position relative to the opening 7,the pin 13 on the lower one of the plates 10 is inserted into the properopening of the'series 14 provided in the disk for engagement by saidpin, the plate 10 having sufficient pivotal movement upon the bent endsof the lugs 11 as pivots to permit the disengagement of the pin 13 withone of the openings when it is desired to shift the plate in position.`When the negative is to be inserted in the frame, the lower plate 10will be secured in position at the desired point below the centralopening 7 in the disk and the upper plate will be moved upward highenough to permit the lower margin of the negative to be brought intoengagement with the lugs 12 upon the lowerplate and leave the uppermargin of the negative below the lugs 12 upon the upper plate. ln orderto keep the upper plate entirely out of the way while positioning thenegative over the opening, it may be forced upward until the spring-lug16 engages with the hook 1S at the upper portion of the disk and left inthat position until the negative is in position, and the upper plate 10may be brought down into engagement with the negative to hold itsecurely.

ln order to support the middle portion of the negative, which lies overthe central opening 7 in the disk, a slight swell 23 is provided in thedisk on either side of said opening, as shown, the swells being all ofsuch size that when the negative is held by the lugs 12 upon plates 10the rear surface of the negative will lie in contact with the saidswells. Y

After the negative has beelrinserted between the spring-actuated plates10 it will be securely held regardless of the position into which thedisk 6 is turned, and Vthe negative may be shifted up and down over thecentral opening 7 by simply disengaging pin 13 of the lower plate 10from the opening in which it is inserted and moving the plate up anddown to the desired point. As the upper plate 11 is connected With thelower plate by means ot' springs, it is unnecessary tomove the upperplate separately. Y.

As the slots 9, placed in the disk 6, are long enough to permit theplates lO to come into contact, the said plates are adapted to holdnegativesof widely-different sizes.

The provision of the adjustable clamping means upon the rotarybase-plate of the retouching-frame permits the negativetesupportedthereon to be turned instantly into any position which the retoucherIindsmost convenient for working upon the negative and at the same timeprevents any accidental shifting of the negative upon the rotarybase-plate.

TNhile I have described and illustrated the preferred form of embodimentof the invention, it is to be understood that changes in the exact form,proportions, and mode of assemblage of the elements may be made withoutdeparting from the spirit of the invention or sacrificing any of itsadvantages.

Having thus described the construction and operation of my invention,what l claim as new, and desire to secure by Letters Patent, is-
